Despite the great socioeconomic burden of stroke, there have been few reports of stroke statistics in Korea. In this scenario, the Epidemiologic Research Council of the Korean Stroke Society launched the "Stroke Statistics in Korea" project, aimed at writing a contemporary, comprehensive, and representative report on stroke epidemiology in Korea. This report contains general statistics of stroke, prevalence of behavioral and vascular risk factors, stroke characteristics, pre-hospital system of c

BACKGROUND AND PURPOSE: Controversy exists over the prognostic significance of perihematomal edema (PHE) in intracerebral hemorrhage. We aimed to determine the association of early PHE and clinical outcome among participants of the Intensive Blood Pressure Reduction in Acute Cerebral Hemorrhage Trial (INTERACT) studies. METHODS: Pooled analyses of computed tomographic substudies in the pilot phase (INTERACT1) and main phase (INTERACT2), both international, prospective, open, blinded end point, r

BACKGROUND AND PURPOSE: We investigated clinical and radiological characteristics of ischemic stroke patients with Takotsubo-like myocardial dysfunction. METHODS: From multicenter stroke registry database, ischemic stroke patients who underwent transthoracic echocardiography were found. Among these, patients were classified if they had specific ventricular regional wall motion abnormalities discording with coronary artery distribution, such as apical (typical pattern) or nonapical ballooning (at

BACKGROUND AND PURPOSE: The objective of this study was to investigate the potential benefits of statin therapy on mortality and stroke recurrence after cardioembolic stroke. METHODS: In this retrospective observational study, we analyzed data from 535 patients with first-ever cardioembolic stroke. Patients were classified into nonstatin, low-potency statin, and high-potency statin groups. The primary outcomes were time to mortality and time to recurrent stroke. RESULTS: The mean duration of fol

Background There is insufficient evidence on the effect of statins, particularly high-intensity statins, in patients with acute ischemic stroke and atrial fibrillation. We investigated the impact of statins on the outcomes in these patients, including those who might be vulnerable to statin therapy and those without clinical atherosclerotic cardiovascular diseases. Methods and Results A total of 2153 patients with acute ischemic stroke and atrial fibrillation were enrolled in the present nationw

We aimed to develop a novel prediction model for early neurological deterioration (END) based on an interpretable machine learning (ML) algorithm for atrial fibrillation (AF)-related stroke and to evaluate the prediction accuracy and feature importance of ML models. Data from multicenter prospective stroke registries in South Korea were collected. After stepwise data preprocessing, we utilized logistic regression, support vector machine, extreme gradient boosting, light gradient boosting machine

Depression occurring early after stroke was associated with the increased risk of recurrent cerebrovascular events in ischemic stroke survivors. Care plan to detect and manage depression should be implemented to prevent recurrent stroke.

BACKGROUND: There is limited information regarding return to driving after stroke. AIMS: To determine the frequency and predictors of return to driving within 1 month of acute stroke in younger (age 18-65 years) adults. METHODS: POISE (Psychosocial Outcomes In StrokE) was a cohort study conducted in Australia between October 2008 and June 2010. Consecutive patients (age 18-65 years) with a recent (≤28 days) acute stroke were recruited. Validated demographic, clinical, mental health, cognitive, a
